Application filed January 2a, 1908. Serial No. 412,308.

To all whom it may concern:

Be it known that I, JAooB J. SHTUOHKA, of Rochester, in the county ofMonroe and State of New York, have invented a new and useful Improvementin Means for Flushing and VentilatingClosets, which improvement is fullyset forth in the following specification and shown in the accompanyingdrawings. V

' Myinvention relates to water-closets and mechanism connectedtherewith, and it has for its object among others to provide improvedmeans and devices for the better flushing and ventilating of the bowl,and for controlling the flow of air and water during the process offlushing. The pipe for conducting the Water for flushing comprises threecylindrical parts or members joined by screw-threaded portions andhaving a common axis, said three portions collectively constituting ahousing or inclosure for the flushing valve and valve-seat together witha lengthened tubular holder or carrier for 'the valve, with numerousincumbent parts and devices.

Other objects. and advantages of the invention will be brought out andmade to appear in the following description and the novel featurespointed out in the appended claims, reference being had to theaccompanying drawings which, with the reference numerals marked thereon,form a part of this specification. a

Fig. 7 is a transverse section'of parts taken onthe dotted line 0 in Fig. 4. Fig. 8 is a transverse section of parts onthe dotted line (Z in Fig. 4. Fig. 9 is a plan of the valve-seat and theend of the valve-chamber, seen as indicated by arrow '6 in Fig. 4. Fig.10 is an axial section of the valve-seat,

detached. Fi s. 3 to 10 inclusive are drawn to various scal es largerthan that of Figs. 1 and 2.

Referring to .the parts shown 1, Figs. 1 and 2, is a bowl ofsubstantially common construction in water-closets, 2 being an air-pipefor ventilating and 3 an inflow water-pipe for flushing the bowl, thewater being supplied through an inflow pipe 4. The flushpipe 3 has abranch coupling 5, Figs. 1, 2 and 4, there being a connecting pipe 6threaded into said coupling 5 and leading obliquely upward to a similarinverted coupling 7 on the air-pipe 2 forming a continuous passage forair between the two pipes 2 and 3, which, except as to the pipe 6, areindependent of each other and both being independently connected withthe bowl 1. Above and attached to the coupling 5 by threaded portions isa short pipe or thimble 8, Figs. 1, 4

and 9, constituting a valve-chamber, holding a valve-seat 9 this thimbleforming a connection between the coupling 5 and a T- coupling 10receiving the discharge end of the supplypipe4. Above the coupling 10and screw-threaded thereon is a short tubular body or casing 11, Figs.1, 3, 4 and 7, closed at its upper end by a screw-cap 12, said casing,the T-couplinglO and the valvechamber 8 being coaxial.

Within the coupling 10 is a conical valve 13, Figs. 4, 5 and 8, adaptedto rest upon and within the valve-seat 9, said valve being held orsuspended'at the lower end of a length: ened tubular part or member 14axially within the coupling 10 and the casing 11, extending at its upperend centrally through and above the screw-cap 12, as shown in Figs. 1and 4. A lever or arm 15,'Figs. l and 2, is provided for working thevalve 13, held to swing on a bearing vertically in a bracket 16 securedto a part of the water-pipe 3, one end of the ever being joined to theupper projecting end of the holder 14 for the valve by strapsorrconnectors 17, Figs. 1, 2, 3 and 4.

A downward pull upon the free end of the lever at any time will serve tolift the valve 13 off of its seat 9 and allow a down-rush of waterthrough the pipe 3 into the bowl 1.

The valve 13 is formed with a short stem 18, Figs. 4, 5 and 8, extendingupward into the lower end of the hollow holder 14, being retained inplace by a pin 19 passing transversely through both the holder and thestem. The stem is smaller in diameter than the bore of the holder andbeing loose on the pin 19 allows the valve to have limited universalmotion so as to readily adjust itself to the seat 9 and so form a tightjoint, therewith, the seat being-commonly provided with an india-rubberring 20, Figs. 4, 9 and 10, to directly receive the valve. The stem 18being smaller in diameter than the bore of the holder 14, as stated,admits of the flow of air or water through the holder. The lower portionof the valve holder 14 is preferably made larger in diameter than theupper portion, at the junction of which unequal parts, and substantiallymidway of the length of the holder, is formed an expanded part orcylindrical head 21, Figs. 4, 5, 6 and 7. This head is reduced at itsends and provided with threaded rings 22 22 holding cup-shapedpacking-rings 23, as of leather, turne'd in oppositedirections to meetand press theinner surface of the casing 11, as shown, making awater-tight joint therewith, the head acting as a piston-head moving inthe cylindricalcasing 11.

The head 21 is pierced longitudinally by passages 24, Figs. 5 and 7 forair or water, normally closed by a yielding ring 25, as of leather,Figs. 4 and 6, pressed against the lower end of the head by a spring 26coiled upon the tubular holder 14, and resting at its lower end upon aring or disk 27 resting against the cross-pin 19 of the holder 14 Onaccount of the openings or passages 24 through the head 21 the valve 13may be, at any time, quickly lifted from its seat 9 by pulling the freeend of the lever 15 downward, as stated, the air or water above the head21.passing rapidly downward through said openin s to supply the partialvacuum beneath. The upper portion of the valve holder 14 is providedwithapair of stiif cupshape fibrous packing-rings or bodies 28 28 turnedbase to base, as shown in Figs. 3, 4 and 5, with their 0 en edgespressing respectively the inner sur ace of the screw-cap 12 and acircular plate 29 on the holder 14, resting upon an internal shoulder 38of the casing 11. A spiral spring 30 between the plate 29 and the head21 serves normally to close the valve by pressing it and the holder 14downward, the'lifting of the holder by means, of the lever15 acting tocompress the spring.

When the valve 13 is lifted at any time, as

stated, the water above it under pressure,

rushing downward through the pipe 3 will draw quantities of air downwardthrough the connecting pipe 6 into the pipe 3 to ventilate the latterand the bowl. The pipe 3 is normally filled with air below the valve 13,with small quantities of air in the upper end of the casing 11.

The upper small part of the tubular holder 14 is substantially filled byan elongated corepiece or plug 31, Figs. 3, 5 and 7 with pointed lowerend to meet a valve-seat 32 for the purpose of closing the opening orpassage through the holder 14 when wished. The

plug 31 is threadedat 33 in the upper end of the part 14 and formed witha transverse slot at its upper end, as shown in Fig. 3, to

wished to wholly stop this flow the plug is turned fully down againstthe seat 32, as stated. I also provide a longitudinal open ing orpassage 35 through the wall of the casing 11, Fig. 4, communicatingthrough an opening 36 between the interiors of the coupling 10 and thecasing 11, this passage being controlled, and closed when necessary, bya thumb-screw 37 The passage-through the hollow "holder 14 and thepassage 35 in the wall of the casing 11, both communicating between theinteriors of the coupling 10 and the casing 11, afford two independentmeans of controlling and regulating the flow of small quantities ofLwater one way or the other between said two parts 10 and 11, this flowbeing caused by the vertical movements of the piston-head 21" during theupward and downward movements of the valve, above de scribed. In somecases it may not be convenient to operate the plug 31 in which cases thethumb-screw 37 may be employed.

The operation briefly described is as follows :When the valve 13 islifted off its seat by a downward pull on the free end of the 'lever 15,the water is permitted to flow through the supply pipe 4 under pressureand rushing downward through the pipe 3 the said water draws quantitiesof air downward through the branch pipe 6 into the pipe 3, thusventilating the latter and the bowl. It is to be noted that the pipe 3is normally filled with air below' the valve 13 when the latter. isseated and that there will be a small quantity of air in the upper endof the casing 11 above the valve.

The aspirated air from the bowl will in a great measure be drawn throughthe'branch 6 and pipe 3 and down through thewater seal into the soilpipe and thus removed. Any that is not thus removed will be. sothoroughly washed in its passage through the water offensive.

What I claim as my invention and desire to secure by Letters Patentis 1. The combination, with a water pipe and an air pipe adapted to beconnected to a closet bowl, of a connection between these pipes andmeans for introducing water into pipe as to become entirely inthe waterpipe above the connection to exhaust air from the bowl by way of the airpipe and at the same time flush the bowl.

2-. The combination, with a water pipe and an air pipe adapted to beconnected to a closet bowl, of a connection between these pipes andmeans for introducing a predetermined quantity of water into the waterpipe above the connection to exhaust air from the bowl by way of the airpipe and at the same time flush the bowl.

The combination with a closetbowl of separate air and water pipesconnected therewith, a connection between the said pipes outside of thebowl and means for introducing a predetermined quantity of water intothe water pipe above the connection to exhaust air from the bowl by wayof the air pipe and at the same time flush the bowl.

4. The combination, with a water pipe and an air pipe adapted to beconnected to a closet bowl, of a connection between these pipes, a watersupply pipe, and means embodying devices intermediate the supply pipeand the point of junction of said connection with the water pipe forintroducing water into the water pipe above the connection to exhaustair from the bowl by way of the air pipe and at the same time flush thebowl.
